To all whom it may concern:

.f the mechanism hereinafter described.

ln the drawings forming a part hereof, Figure 1 is a plan view of my improved binder. Fig. 2 is a section'taken on the line 2 2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a plan. showing theback plate with some ofthe mechanism secured to it, parts being shown in section. Figs. 4 and 5 are detailed views showing parts of the mechanism.

Throughout the various views similar reference characters designate similar parts.

The binder 1 is provided with a back plate 2, which is formed with an integral and centrally-located longitudinal web 3, which extends from near one end a little more than half-way, where it-terminates in an enlarged end 4, which is providedwith a cylindrical bore 5. This web 2 is also provided with a second enlargement 6 near its other end, which projects above and on each side of said web, Ias willhereinafter appear.

Overlapping and extending beyond the enlargement 4 are parallel webs 7 and 8, which serve to stiflen the structure and protect the clamping mechanism,`and between the other ends of these webs 7 and 8 is a lug 9, with a bore 10, which is concentric with the axis of the bore 5. This lug 9 is connected with a longitudinal web 1 1 .at one side, which termi nates in a second'lug 12 near one end of the back. The lugs 9 and'12 and the web 11are preferably made integral with each other and the back 2. A lug 13, integral with the back 2, is placed symmetrical with the lug 12 with regard l to the axis of the bores 5 and 10. Transverse iianges 14 and 15 extend from the end ofthe back 2 from the lugs 12 and 13,

and a similar flange 16 is placed at the other end of the back 2 with longitudinally-extending lugs 17 and 18. The vflanges 14, 15, and

16 are 'about the same heightsas the edges of the back 2, which is concaved on the face the lugs protrude from, andthe lugs 12, 13, 17,

and 18 extend above these flanges, as shown in y Fig. 2. Guide-plates 19 and 20, withl upwardly and inwardly turned flanges 21 and 22, are secured to thejklugs 12 and. 13 and 17 and 18, respectively; and thesejplates 19 and 20I protrudejbeyond thenedgesof thebackj, as, shown in Fig. 3.

key, engages a spindle 24, with a collar 25, which forms a journal in the bore 10, and beyond this collar the spindle isv reduced at 26 to form a second collar 27., beyond which the spindle is screw-threaded at 28 to the second journal 29 which is at the end of the spindle and ts in the bore 5. A slotted plate 30vfits the reduced portion 26 and rests against the lug 9 to hold the spindle 24 against all motion in the direction of its axis. v 2 A nut 31 engages the screw-threads 28 and slides backward and forward on the back 2 When'the spindle 24 is rotated. This'nut ,31 is preferably rectangular in cross-sectionv and is provided with ratchet-teeth 32 on each side, and its inner end is formed into a cam 33,

tagiA key 23, which may be an ordinary clockf which is adapted to engage and separate the upwardly and forwardly disposed ends of the spring-dogs 34 and 35, which are iixed at 36 to the web 3. The dogs 34 and 35v are each bent upwardly and then downwardly, as

shown 1n Fig. 2, so as to engage the pawls 58 1 and 59 as will appear below.

The clamping members 37 and 38 may be of any suitable form, although they are preferably made, as shown, with curved sides39 and 40 and projecting bottoms 41 and 42, which havel extensions'43, which are between the guides 19 and 20 and the flanges 14, 15, and 16, and these extensions 43 are connected with the curved sides 39and 40 by means of webs 44, so that the clamping mem-l bers 37 and 38 may slide transversely of the back 2, but in no other direction. `Telescoping binding-fingers 45, 46, 47, and 48 unitel thel upper edges of theclamps 37 `and 38. While only four such iingers are shown, itis obvious that as many may be used as desired. Running parallel with these', fingers and below the plane they occupy are rods v49, which each have one end secured to the sides 39 and 40, respectively, and the other end of v 'i each rod passes through a hole 51 in the web 3. Springs 52 encircle these rods, each having one end pressing against the web 3, and the other against the sides 39 and 40. Only one set of such springs and rods are shown -for convenience, although it is preferable for IIO which protrude studs 54, to which are piv-A oted toggle-levers 55, the other ends of said levers being 'connected to a slide 56. The studs 54 arepreferably screw-threaded at `their' lower'y ends to. engage the bottom 41 and 42, andthe levers 55 are connected to' the 'slide'56 by rivets, which also pass through small `washers57.

Centrally located on the slide 56 are pivoted'pavvls 58'and'59, vwhich are pivoted at 60 andprovided with teeth 61, which are adapted to engage the teeth 32 on the nut 31. 'Ihese'pavv'lsy `are also provided with cams 62, which are adapted to engage the ends of the A spring 63 at the rear of thesepaiwls tends to-bring them together, so that the teeth 61 are separated against the action of this spring.

- The'slide 56 is held in position and against all movement save that in the direction of its length bybands 64, which are secured to the lugs'Q and`6 by pins k65, which pass through perforations therein, as clearly shown in Figs.

l'and 2.

In Fig. 6 is shown a portion of a page 66 With a slot 67, adapted to lit over one of the telescoping fingers, and the lines 68 in Fig. 1

show the maximum the binder 1 may be opened to receive pages 66. The lines 69 show the minimum opening.

, From` the above the operation of my improved binder Will be readily understood. Assuming the parts to be in the position indicated in Fig. 1, the pages 66 are properly inserted, as they may be each independently of the others, and When a sufficient number are in place the clamps 37 and 38 are brought together, thereby causing the toggles 55 to make the slide 56 move in the direction of the key 23. During this movement the pawls 58 and 59 are caused to spread outwardly by the cams 62, which ride over the endsof the dogs 34 and' 35 and engage the teeth 32 on the nut 31, thereby locking the clamps 37 and 38 Iagainst the pages 66. This is ordinarily found suiii'cient but should it be found desirable to;clamp the. ages more rigidly together this may be done y turning the key 23 and revolving the shaft 24, thereby bringing the nut 31v toward the key 23, together with the slide 56, ,and thereby further tightening the clamps 37 'and' 38. These clamps are separated Abythe action of the spring 52 when the nut 31 ismoved away from the key 23 by turningthe shaft v24, and when the cam 33 on this' nut engages the dogs 34 and 35 it sepavrates them and causes the pawls 58 and 59 to `separate against the action of the spring 63 and release the nut 31, so that the springs 52 are free to separate the clamps 37 and 38 with rapidity. The nut 31 is then brought forward until the dogs 34 and 35 are clear of the cam 33, when the clamps may be again closed, as described above. The key 23 is removed from the binder at any time when pages are not being removed or inserted, as it is then unnecessary. From this it is apparent that my improved binder inay be clamped and unclamped with rapidity and ease for the removal or linsertion of pages and that all pages which are inserted will be securely held.
